A & B started a partnership business. A's investment was thrice the investment of B and the period of his investment was two times the period of investments of B. If B received Rs 4000 as profit , what is their total profit? | [
"34000",
"None of these",
"28000",
"32000"
] | C | Explanation :
Suppose B's investment = x. Then A's investment= 3x
Suppose Bs period of investment = y, then A's period of investment = 2y
A : B = 3x * 2y : xy
= 6 : 1
Total profit * 1/7 = 4000
=> Total profit = 4000*7 = 28000. Answer : Option A | AquaRat_train |

A is twice as good a workman as B and together they finish a piece
in 18 days. In how many days will A alone finish the work? | [
"29 days",
"32 days",
"54 days",
"27 days"
] | D | Sol. (A’s 1 day’s work):)(B’s 1 days work) = 2 : 1.
(A + B)'s 1 day's work = 1/18
Divide 1/18 in the ratio 2 : 1.
:. A’s 1 day's work =(1/18*2/3)=1/27
Hence, A alone can finish the work in 27 days.
